Serious books on math, physics and related sciences usually have covers which are quite boring and visually not very attractive. (Books that have something to do with Universe are a common exception, but when you see a few of them you have seen them all.) But sometimes, covers are really interesting and/or beautiful. Here you are encouraged to present examples of such nice covers of serious science books. Please provide either a picture of the covers or a link to the picture!

Haha, true. I like books like this because its like someone is telling you a story (Formulas spoil everything). :D
I suppose it all originates from the fact that I was told things like theory of relativity as bedtime stories.
